Cowden E. W. #57 (API 42-495-32282) is a well in Winkler County operated by Heifer Production Company LLC, completed October 21, 1989 and listed as no production on the RRC schedule.

The RRC has issued one drilling permit, issued September 21, 1989, permitted to 3,200 ft.

It was permitted by Thomas, J. C. and has since transferred to Heifer Production Company LLC on the wellbore schedule.

Completion filings report one formation top, including Yates.

Its lease has reported 412K barrels of oil and 570K mcf of gas since January 1993, last reporting in July 2026. The lease carries 53 wells, so these are lease totals, not this well alone.

The sources disagree, which usually means a transfer or a lease-level production filing by a different entity. Petrora goes with the schedule.
